Review
OBJECTIVE
To review hearing and surgical outcomes after reconstructive middle ear surgery in class 4 congenital middle ear anomalies (CMEA), e.g., patients with oval- or round window atresia of dysplasia.
DATA SOURCES
Pubmed/Medline, Embase and Cochrane library.
REVIEW METHODS
Articles containing data on hearing outcomes and complications after reconstructive ear surgery in class 4 anomalies were analyzed and critically appraised. The following data were included and reviewed: patient demographics, audiometric testing, surgical techniques, complications, revision surgeries and their outcomes. Risk of bias was determined, and GRADE certainty of evidence was assessed. Primary outcomes were postoperative air conduction thresholds (AC), change in AC, and success rates (closure of the ABG to within 20 dB), the occurrence of complications (most importantly sensorineural hearing loss) and the long-term stability of hearing results (> 6-month follow-up) and occurrence of recurrence of preoperative hearing loss.
RESULTS
Success rates varied from 12.5 to 75% at long-term follow-up with larger cohorts reporting success rates around 50%, mean postoperative gain in AC varied from 4.7 to 30 dB and - 8.6 to 23.6 dB at, respectively, short- and long-term follow-up. No postoperative change in hearing occurred in 0-33.3% of ears, and recurrence of hearing loss occurred in 0-66.7% of ears. SNHL occurred in a total of seven ears across all studies of which three experienced complete hearing loss.
CONCLUSION
Reconstructive surgery can be an effective treatment option which should be considered in patients with very favorable baseline parameters, while also considering the substantial risk of recurrence of hearing loss, the possibility of unchanged hearing despite surgery and the rare occurrence of SNHL.

Meta-Analysis Review
OBJECTIVE
Juvenile Otosclerosis (JO) and Congenital Stapes Footplate Fixation (CSFF) are rare ossicular chain disorders seen in the paediatric population and present with conductive hearing loss. Ongoing controversy exists regarding the role of surgical intervention in JO and CSFF given the poorer hearing outcomes and complications when compared with surgical intervention for adult otosclerosis. The objective of this study is to assess the published data on the surgical outcomes of JO and CSFF in order to guide clinicians and counsel patients on the various medical options for these disease entities.
METHODS
A systematic review of MEDLINE, EMBASE and Cochrane was performed with inclusion criteria of children with JO or CSFF and hearing outcomes following stapes surgery. Studies identified by the search were reviewed and assessed by two independent reviewers in line with the PRISMA guidelines.
RESULTS
464 articles were initially reviewed and 28 articles met inclusion in the systematic review and meta-analysis. A total of 810 ears (473 and 337 cases of JO and CSFF respectively) underwent stapes surgery. Average age at time of surgery for JO and CSFF was 14.3 and 10.2 years old respectively. The mean pre-operative Air-Bone-Gap (ABG) for JO and CSFF was 31.8 ± 5.2 dB and 39.4 ± 10 dB respectively. Following stapes surgery, the mean post-operative ABG for JO and CSFF was 9.6 ± 6 dB and 19.2 ± 12.5 dB respectively. Surgical success rate (defined as ABG <10 dB) was 81% for JO and 41% for CSFF. Mean ABG gain for JO and CSFF was 24.8 dB (95% CI: 18.6-33.1) and 22.6 dB (95% CI: 18.4-27.8) respectively. The reported number of dead ears was 4/473 (0.8%) for JO and 2/337 (0.6%) for CSFF. 23 cases (2.8%) reported sensorineural hearing loss (SNHL) >10 dB.
CONCLUSION
CSFF was associated with poorer hearing outcomes compared to JO, however both entities showed similar improvement in ABG post operatively. Counselling patients and their families on the surgical success rates and complications of JO or CSFF is an important part of the decision making process when deciding between a surgical option or conservative measures such as hearing aids.

Meta-Analysis
INTRODUCTION
Iatrogenic injury to the chorda tympani (CT) is a well recognized, although potentially underestimated, consequence of stapes surgery. This study aims to review the currently available literature to determine the incidence and prognosis of taste disturbances in these patients.
DATA SOURCES
PubMed, Embase, and Cochrane Library databases.
METHODS
Databases were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Search terms included (chorda tympani OR gustatory OR taste OR chemosensory OR dysgeusia OR nervus intermedius) AND (ear surgery OR middle ear OR stapes OR stapedectomy OR stapedotomy). Patients with prospective data collection including preoperative data were further divided by methodology into "objective" and "subjective" assessments of taste dysfunction. A systematic review was performed for all included studies, with meta-analysis using a random-effects model was used for those with comparable methodology and patient populations.
RESULTS
Initial search yielded 2,959 articles that were screened according to inclusion and exclusion criteria. Once duplicates were removed, seven studies were identified, representing 173 patients with subjective testing (all seven studies) and 146 with objective testing (five studies). Eighty of 173 patients (46.2%) noted a disturbance in taste at early follow-up, whereas as 26 of 173 (15.0%) noted long-term problems. Objective methodology and result reporting were heterogenous and not amenable to pooled meta-analysis for all studies included.
CONCLUSION
Changes in taste occur relatively frequently after stapedectomy. Surgeons should continue to counsel prospective patients as to the risks of both short- and long-term taste disturbances.

Meta-Analysis Review
OBJECTIVE
To compare the efficacy and safety characteristics of different materials used for oval window sealing during stapedotomy.
METHODS
A systematic review was conducted according to the PRISMA guidelines. Published international English literature from January 1, 2000 to December 2021 was screened, checking for studies that compared different materials utilization in patients undergoing stapedotomy surgery for otosclerosis or congenital stapes fixation. Data related to the efficacy and safety of each material were extracted. The primary outcome measure was the air-bone gap (ABG) closure after surgical intervention.
RESULTS
Six studies were included in the metanalysis. Because of the heterogeneity of the treatments adopted, we assessed the use of the fat compared to all other treatments, and the use of the gelfoam compared to all other treatments. In the former analysis (fat vs others) we did not identify differences in ABG closure between the groups (p = 0.74), with a low heterogeneity of the results (I = 28.36%; Hedge's g = 0.04, 95% CI - 0.19 0.27); similarly, we did not identify differences between the use of gelfoam and other treatments (p = 0.97), with a low heterogeneity of the results (I = 28.91%; Hedge's g = 0.00, 95% CI - 0.20 0.21).
CONCLUSIONS
Numerous options are available for oval window sealing during stapedotomy, with acceptable safety and effectiveness profiles. Based on the current data, no definitive recommendation can be made regarding the choice of one material over another, and the convenience of sealing over no sealing at all.

Meta-Analysis
OBJECTIVE
This study is to compare the hearing outcomes and complications of stapes surgery and cochlear implantation (CI) in patients with far-advanced otosclerosis (FAO).
DATA SOURCES
A comprehensive electronic search of PubMed/MEDLINE, Scopus, Web of science and Cochrane Library was conducted in June 2021 for articles in the literature till this year.
STUDY SELECTION
Studies are published in English language, conducted on human subjects, concerned with comparison of CI and stapes surgery in the management of FAO, not Laboratory study and not Opinion study. The current review followed the guidelines of preferred reporting items for systematic reviews and meta-analysis statement 2009 (PRISMA).
DATA EXTRACTION
Twenty-six studies were included with 334 patients in CI group and 241 patients in stapes surgery group. Comparison between both groups was done in terms of postoperative complications, audiological outcomes, rete of revision surgery and patients' satisfaction rate.
RESULTS
Postoperative complications rate was significantly lower in CI (13.6%) than stapes surgery (18.6%). CI had a significantly lower rate of revision surgery (8.1%) than stapes surgery (16.4%). CI had a better mean for pure tone average (29.1 dB) than stapedectomy (52.3 dB) while stapes surgery had a higher mean for recognition of monosyllables and disyllables than CI. CI had significantly higher satisfaction rate than stapes surgery.
CONCLUSION
Both Stapes surgery and CI are reliable treatment options for FAO with close success rates. Statistics of CI are greater than stapes surgery and CI has a consistent improvement in audiometric outcomes in comparison to stapes surgery.

BACKGROUND
The primary aim was to determine the clinical success rate after treatment for talocalcaneal (TCC) and calcaneonavicular coalitions (CNC). The secondary aim was to evaluate the complication, recurrence and revision rate.
METHODS
A search was carried out in MEDLINE, EMBASE and Cochrane Library. Methodological quality was assessed using the Methodological Index for Non-Randomised Studies (MINORS) criteria. The primary outcome was the clinical success rate and was pooled per type of coalition and treatment modality. 95% Confidence Intervals (CI) of the success rates were calculated. Secondary outcomes included complication rates, coalition recurrence rates, revision rates and pain improvement using the Visual Analogue Scale (VAS). A sub-analysis on interposition material was performed.
RESULTS
43 articles comprising of 1284 coalitions were included, with a pooled mean follow-up of 51 months. Methodological quality was fair. The overall pooled success rate for TCCs was 79% (95% CI, 75%-83%). Conservative treatment, open resection and arthroscopic resection of TCCs resulted in success rates of 58% (95% CI, 42%-73%), 80% (95% CI, 76%-84%) and 86% (95% CI, 71%-94%), respectively. CNCs have an overall success rate of 81% (95% CI, 75%-85%), with 100% (95% CI, 34%-100%), 80% (95% CI, 74%-85%) and 100% (95% CI, 65%-100%) for conservative treatment, open resection and arthroscopic resection, respectively. Pooled complication rates of 4% (95% CI, 3%-7%) for TCCs and 6% (95% CI, 4%-11%) for CNCs were found. The success rates of resection with and without interposition material for TCCs were 83% (95% CI, 78%-87%) and 79% (95% CI, 65%-88%), and for CNCs 81% (95% CI, 76%-86%) and 69% (95% CI, 44%-85%), respectively.
CONCLUSION
Treatment of tarsal coalitions can be considered good to excellent as well as safe, with an overall clinical success rate of 79% for TCCs and 81% for CNCs. Arthroscopic resection of the coalition appears to be non-inferior to open resection of TCCs and CNCs.

Meta-Analysis Review
OBJECTIVE
To compare the efficacy and safety characteristics of endoscopic and microscopic stapes surgery based on current evidence.
METHODS
A systematic literature search was conducted of three medical databases, focusing on randomised, controlled studies or observational studies. Data related to the efficacy and safety of each technique were extracted. Outcome data were summarised using the pooled mean differences or pooled odds ratios, along with their 95 per cent confidence intervals.
RESULTS
Thirteen studies were included in the meta-analysis. Success rate was evaluated by estimating air-bone gap improvement; this revealed comparable outcomes for the two techniques (mean difference = -0.20; 95 per cent confidence interval = -0.53, 0.14). No statistically significant difference was detected concerning post-operative complications, except for dysgeusia (odds ratio = -1.12; 95 per cent confidence interval = -1.97, -0.28) and pain (odds ratio = -2.00; 95 per cent confidence interval = -2.97, -1.04), which favoured the endoscopic approach.
CONCLUSION
Though both techniques result in commensurate outcomes concerning success rate, post-operative pain and dysgeusia favour the endoscopic approach. Further high-quality studies are needed to adequately compare the two methods.

OBJECTIVES
Stapes surgery has evolved from its origins in 1956. Microscopic assisted stapedotomy remains the most common technique but the introduction of endoscopic ear surgery has led to some units using this new approach. The endoscope delivers a wide angled, contextual view of the stapes, and associated pathology. This systematic review provides a critical analysis of the current published endoscopic data, allowing comparison to the established microscopic technique.
DATA SOURCES
Six databases (PubMed, Medline, Cochrane database, AMED, EMBASE, and CINAHL) were searched for studies within the last 10 years.
STUDY SELECTION AND DATA EXTRACTION
English language articles including 5 or more cases were included. Primary outcomes included audiological results and reported complications. Data was extracted according to PRISMA guidelines.
RESULTS
Thirteen papers were identified comprising 361 endoscopic stapes surgeries. Postoperative temporary facial nerve weakness was reported in 3 patients (0.8%) which all resolved within 4 weeks. Chorda tympani injury occurred in 21 cases (5.8%) and vertigo in 61 (16.9%). The audiometric outcomes of endoscopic stapes surgery were available for 259 patients and showed air bone gap closure rates of 71.4% (0-10 dB), 25.9% (11-20 dB), 2.3% (21-30 dB), and 0.4% (>30 dB).
CONCLUSIONS
Endoscopic stapes surgery has similar audiometric outcomes compared to the traditional microscopic approach with air bone gap closure values of <20 dB in 97.3% of cases. However, the complication rates of chorda tympani damage, postoperative dysguesia, and tympanic membrane perforation for endoscopic stapes surgery are high. Caution should therefore be taken before undertaking stapes surgery with the endoscopic technique. Further studies are required to prove superiority over well established existing microsurgical methods.

Review
OBJECTIVE
These days, the gold standard procedure for otosclerosis treatment is stapes surgery. The endoscopic approach of the procedure is gaining popularity as endoscopic ear surgery develops across the globe. The main objective of this study is to gather and compile well-documented and reliable data regarding surgical outcomes for the endoscopic approach to stapes surgery up to this date.
MATERIALS AND METHODS
Publications in English were searched in the PUBMED/MEDLINE database and were systematically reviewed. A total of 16 articles were reviewed according to the inclusion criteria, obtaining a total of 573 patients managed surgically for otosclerosis, using an endoscopic approach. Data were systematically extracted and compared across variables.
RESULTS
Data were obtained as follows: mean age of 43 years; female proportion of 60%; 3 mm endoscope diameter of 51%, 4 mm of 39%; titanium piston-type prostheses of 52% and Teflon of 48%; length of the prosthesis (mode) was 4.5 mm; 0.6 mm diameter of the piston of 81% and 0.4 mm of 19%; mean surgical time was 55 min. Hearing results, mean preoperative air-bone gap (ABG) 31 dB; mean postoperative ABG 9 dB; ABG improvement of 22 dB; an ABG closure rate to 20 dB or less of 92% and an ABG closure rate to 10 dB or less of 77%. Complication rates: intraoperative tympanic membrane perforation of 5%; postoperative vertigo of 11%; postoperative dysgeusia of 10%; reported a postoperative neurosensorial hearing loss of 0.2%; reported gusher phenomenon of one case (0.2%).
CONCLUSION
Endoscopic stapes surgery is completely achievable using 0º angle and 4-mm-diameter sinus surgery endoscope. Instrument availability should not be an obstacle to the development of this type of surgery in any otolaryngology department. Audiological outcomes are comparable to microscopic approaches.

Meta-Analysis Review
OBJECTIVE
This meta-analysis is aimed to review and analyze all available data of intraoperative and postoperative results of endoscopic and microscopic stapes surgery.
METHODS
According to the PRISMA statements checklist, this systematic review and meta-analysis were designed. Data were extracted from public databases, such as PubMed, Cochrane, Web of Science, and more. The quality of studies was evaluated using the MINORS scale. Odds ratios (ORs) and 95% CIs were estimated for binary outcome data, while the mean differences and 95% CIs were estimated for continuous data. I and χ tests were used to quantify statistical heterogeneity. If more than ten studies were included in each analysis, funnel plot would be performed to analysis publication bias.
RESULTS
Twelve studies with 620 patients were included in this meta-analysis. Primary outcomes collected in this meta-analysis included average postoperative auditory gain (APAG), postoperative air-bone gap (ABG), the rate of chorda tympani handling and bone curettage, which all showed a statistically significant difference in favor of endoscopy. While only secondary outcomes about postoperative pain and dysgeusia demonstrated a significantly reduced incidence. Furthermore, there was not any statistically significant difference on postoperative dizziness and average operative time between endoscopy and microscopy.
CONCLUSION
Although there is a need for high-quality pooled data in the future, a consistently superior effect of the endoscopic group was still shown in terms of total effectiveness, when compared to the microscopic group. We have reasons to support the application of endoscopy in stapes surgery. The future of ESS, we believe, is blazing bright.
